Problem definition: We study supply chain coordination in a setting with transshipment. We use centralized and decentralized transfer prices as a way to increase supply chain coordination. Academic/practical relevance: The ability to transship can improve channel efficiency by improving the match between supply and demand. We study how human decision makers behave in this setting and provide clear insights to improve coordination. Methodology: We use controlled laboratory experiments with financially incentivized human subjects. We study a broad set of critical ratios under both decentralized and centralized transfer-price settings. In the decentralized transfer-price setting, retailers negotiate a transfer price. In the centralized transfer-price setting, we use two different approaches: theoretical and behavioral transfer price. Both approaches suggest opposite recommendations. Results: Analytically, the optimal transfer price should depend on the critical ratio; but results from the decentralized setting show that participants set prices as if they ignore the critical ratio and instead focus on splitting potential profit from transshipped units in half. However, there is a positive relationship between transfer prices and ordering decisions. Moreover, generalizing the pull-to-center effect, we find that subjects do not place orders that coordinate the supply chain. For the centralized setting, we find that using the theoretical approach does not coordinate ordering decisions and does not improve decisions compared with the decentralized setting. The behavioral approach suggests a transfer price close to product selling price for a high critical ratio and a transfer price below product cost for a low critical ratio. These recommendations lead to coordinating ordering decisions. Managerial implications: We draw two practical conclusions from our research. First, transshipments are unambiguously beneficial, resulting in higher profitability, and, when feasible, should be encouraged. Second, when possible, transfer prices should be set centrally but taking into account subjects’ behavior. Otherwise, price negotiation might lead to better performance.

The current high world sugar prices reflect a major imbalance between global supply and demand, which has reduced stocks to very low levels. Although it remains to be seen whether prices will rise much above current values, it is clear that the supply chain will remain stretched throughout 2010 and this will help to maintain prices at a high level.

Tourism supply chain management has become an important research topic as individual firms no longer compete as isolated entities but rather as supply chains in the tourism industry. Despite the evidence that benefits can be gained to improve profitability, competitiveness, and customer satisfaction, the research on how to manage the tourism supply chain is very limited. This research contributes to the literature by applying the theory of constraints (TOC) with systems thinking to tourism supply chain management. It proposes that the key issue in tourism supply chain management is the coordination of business activities and the TOC with systems thinking can effectively support tourism supply chain coordination of the various links and processes. The article examines the TOC performance measures and the drum–buffer–rope model in the context of tourism management and applies the focusing process of the TOC as a continuous improvement approach for tourism supply chain management. The research findings suggest that, given modifications to the TOC terminology and the principles, the TOC principles can work as an excellent approach to facilitate the tourism supply chain management.

Community Supported Agriculture (CSA) is an alternative form of distributing agricultural products, including fish, consistent with the model of food supply chain shortening. It extends beyond the traditional model of profit maximization and aims at strengthening local interactions with food consumers. The purpose of this article is to assess the feasibility of implementing the CSA model in the Polish carp market, representing the dominant aquaculture product. The research focused on the potential identified on the supply and demand sides of the carp market. The source material was collected through a pilot two-track empirical study conducted in 2019 in the Barycz Valley, where the largest complex of carp breeding ponds is located in Poland, and in Europe. We propose that the following CSA model of direct sales can become a source of specific benefits in the economic, social, and environmental dimensions for the key stakeholders of the supply chain, (i.e., carp producers and consumers). The research results show that in the case of carp production in Poland, CSA may turn out a desirable support for the sale of fish in the future; however, the existing conditions are not yet fully favourable for its development.
